LUIGI DI QALLO, VF LOCKPORT, NEVI YRK.

RTARY CUTTER.

Application led March 24,1922.

To all whom t may concern y Be i Vknown that I, Lumi DI CARLO, a subject or'V the King of Italy, resident ot Lockport, county or" Niagara, and State ot' New York, have inventedV new and useful improvements in Rotary Cutters, or' which the following is a specification, lthe principle of the inventionV being herein explained, and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

My inventionrelates to rotary cutters, and particularly to a manually operated device of this character for cutting macaroni. More particularly, the invention relates to a rotarymacaroni cutter which is provided with a plurality of knives, so that a plurality or' macaroni strips can be cut at one time, means being provided also whereby the width of the macaroni strips can be varied as desired.

The annexed drawing and the following description set forth in detail certain means embodying my invention, the j disclosed means, however, constituting` but two of the various mechanical forms in which the principle of the invention may be applied.

ln said annexed drawing:

Figure 1 represents Va longitudinal section of my improved cutter;

Figure 2 representsa transverse section, taken in the plane indicated by the line I-II, Figure 1; and

Figure?) represents a longitudinal section of a modified i'orm oi: cutter illust-rating the principle of my invention.

Referring tothe annexed drawing, Figure 1, a suitable cylindrical stem :for my improved cutter is indicated by the ordinal 1, the same being formed at one end with a head 2. provide a pair ci grip members or handles 3 and 4, of which the former abuts the head 2 at one end and of which the latter is positioned as desired upon the other end of the cylindrical stem 1 by means of a threaded end portion 5 formed upon the stem 1, and a co-operating nut 6. rihe grip members 3 and 4 are secured to the The inner ends ot the handles 3 and-4 are formed with bushing members 3 and .4', respectively, of uniform thickness, the body portions ot the handles 3 and 4'being of varying thickness for grip -purposes,.as plainly shown in the drawing.

These inner end portions 3 and 4 of the handles 3'and 4 are incased in metallic fer- Eferial No. 546,332.

rules 7 and 8, respectively. Washers 9 and 10 are disposed interiorly ci and adjacent to the iierrules and 8 and between these wash ers, upon the stem 1, is mounted a cutting assembly comprisingan inner tubular support 11 rotatably mounted upon the stem 1 and forming a journal for a plurality ot alternately arranged knives 12 and knifespacers or washers 13, the assembly being completed and held in proper relative longitudinal position by means of nuts 14 and 15 engaging externally threaded end por* tions 16 and 1'! oi the tubular support 11. The two end washers are indicated by theY ordinal 13. lit is evident that any desired number ot knives 12 may be utilized and that the same may be variously relatively spaced by means oi: washers 13 of diii'erent thicknesses or by using different numbers of washers 13. rilhe knives 12 and washers 13 are locked against relative longitudinal movement by means of the proper adjust` ment of the nuts 14 and 15, the whole assembly in turn being securely held between the errules 7 and 3 by means of the proper adjustment of the handle 4 upon the stem 1 which is made possible by the adjustment of the nut 6 upon the threaded portion 5 or the stem 1. The cutter is thus formed dior double hand operation and can be extended or contracted, within reasonable limits, in so far as its over-all cutting dimensions are concerned. The whole knife assembly is rotatable upon the stem 1 and the knives 12 are independently rotatable.

In the form of cutter illustrated by F ig. 3, the main stem consists of a tubular cylindrical member 18, the same being of a diameter considerably greater than that or the diameter of the stem 1, Fig. 1, said stem 13, being, however, 0r a practicable light weight because of its tubular iorm. in this form of cutter l dispense with the tubular sup port 11 and mount the cutters 12 directly upon the stem 18, spacing the same the desired distances by means of washers 13 oi? suitable thickness. rlhe cutting assembly is lined longitudinally by means of a pin 19, which is'tixed transversely oi' the stem 1S and engages slots 21 formed in the washer 20, anda washer 22 at the other end of the cutting assembly which is formed with slots 23 adapted to receive a cotter pin 24 transversely intersecting the stem 18. In this form of cutter, the grip or handle retaining members are formed by caps 25 and 26, ol'

which the cap 25 is rigidly secured to one end et the stem 1S and the cap 26 is removably secured to the other end oi the stem 18 by means et having screw-threaded engagement therewith, so that said cap 25 can be detached to allovv for the placing or removal o'l the cutting,l assembly.

wWhat il claim is:

l. ln a rotary cutter, the combination oit a cylindrical stem; grip members secured to said stem adjacent the ends thereof; a tubular knife support mounted upon said stem intermediate said grip members; a plurality oil disk knives mounted upon said support; means for lixing the knives longitudinally relative te each other; and means for spaeing adjacent knives.

ln a rotary cutter, the combination of a cylindrical stem; grip members secured to said stem adj acentlthe endst'hereof a tubular knife support mounted upon said stem intermediate said grip members, said support having externally-threaded end portions; a plurality olf disk knives mounted upon said support; means 'for spacing adjacent knives; and nuts engaging said threaded support-portions, and adjacent Washers, for fixingthe knives longitudinally relative te each other.

3. In a rotary cutter, the combination of a cylindrical stem having' grip members; a cutting assembly mounted upon said stem intermediate said members, and comprising,- an inner tubular support formed With externally-threaded end portions, nuts engaging said portions, Washers adjacent the inner faces of said nuts, anddisk knives and alternate knife-spacing` washers intermediate said first-mentioned Washers; and other uf'ashei spacing' the cute -faces et said nuts Vand the inner ends et said grip members.

il. ln a rotary cutter, the combination er a cylindrical stem; grip members secured to said stem adjacent the ends thereof, one of said members being Alengitudinally adjustable upon said stem and being termed with an inner-end metallic-incased bushing por-V tion of uniform thickness; atubular knife support mounted upon said stem intermediate said grip members; a plurality oi disk knives mounted upon said support; mee-ns for fixing` the knives -lone'itudiimlly relative to cach other; and means J.or variously siacine' adj aeent knives.
